Personally, my page fetch count is way up because I have a custom deep research agent, I've almost weaned myself off traditional search, but that agent is fetching dozens of pages, like I used to click through a bunch of search results to figure out which are relevant, adjust my query, etc...
That now happens at a higher frequency and volume through my agent.
Could well be, who knows? But, well, then, in a sense you're a part of the problem, causing a DoS for infrastructures and other, human users.
I suspect much of the infra stress is on all the "enhancements" found in the modern web application and the targeted advertising ecosystem
